I just got done doing a compression test on my 2001 330xi with 135,xxx Miles.
The results were:
Cylinder #1:115
Cylinder #2:120
Cylinder #3:120
Cylinder #4:120
Cylinder #5:116
Cylinder #6:115
I thought that good compression was between 142-156psi for a m54, and mine is nowhere near that. So Is the engine good or bad? I had planned on supercharging my Xi, But after these results im not too sure. What would be my next best thing to do, Rebuild engine, engine swap or Sell car?
